As the key enzyme responsible for inorganic carbon uptake in most photosynthetic organisms, Rubisco exhibits poor catalytic activity and reacts promiscuously with oxygen, limiting the rate of photosynthesis. To offset this limitation, many photosynthetic organisms have evolved carbon-concentrating mechanisms (CCMs) that saturate CO2 near Rubisco, maintaining enzyme function and suppressing oxygenation.

Global food security is under constant threat from plant diseases. The evolutionary arms race between the plants and pathogens remains ongoing.

Autotransporters (ATs) are virulence factors found in Gram-negative bacteria that consist of three domains: an N-terminal signal peptide, a central passenger domain, and a C-terminal β-barrel domain. Here, we used RpeA from rabbit enteropathogenic Escherichia coli as a model AT.

Transitioning to renewable fuel oils is essential for replacing fossil fuels, promoting environmental sustainability and improving human health.

RSB Director's Seminar, Professor Adrienne Nicotra, Group Leader in the Division of Ecology & Evolution, RSB, Director of the Australian Mountain Research Facility, Monday the 8th of December 2025.

In this talk, I introduce how white-winged choughs, highly social cooperative breeders, integrate multiple features of alarm and contact communication to coordinate antipredator behaviour and maintain cohesion.

Chloroplasts can sense environmental fluctuations via Ca2+ signaling. Environmental triggers, such as light changes, physical damage and heat waves, can induce distinct Ca2+ signatures in chloroplasts, which may help rebalance photosynthesis and stress responses under fluctuating conditions.

This talk will revisit and contextualise the invasion predicted by Cellarius within a framework of biosecurity risk assessment.

Developmental conditions are powerful drivers of phenotypic plasticity. Environmental factors, such as temperature, can directly program fitness-associated phenotypes, while maternal effects act as indirect cues that shape the developmental environment.
